More often than not, inverters fail to work because of their batteries. Inverter batteries have to be regularly checked for electrolyte levels, distilled water, and salt accumulation. However, poor quality batteries run out of charge despite regular maintenance. Therefore, we bring you 4 top-quality inverter batteries that have none of such issues. Read on to know how they work and how to choose the best one for your needs.

What Are Inverter Batteries?
Inverter batteries provide a small amount of current consistently for longer durations of time. Also known as deep-cycle batteries, these consist of a number of thin metal plates. The electrolyte solution exchanges ions as a part of a chemical reaction.
The electrolyte volume is more so that the chemical reaction takes longer time to produce current. And that’s why inverter batteries are able to provide a consistent amount of current for extended periods. There are several types of inverter batteries based on the electrolytes and chemical systems they house.
What Are The Types Of Inverter Batteries?
1. Lead Acid Batteries:
- These are rechargeable and produce a large amount of current. They usually last for 3–4 years but, require regular maintenance and electrolyte level check. A major drawback is that lead-acid batteries release harmful gases during charging and discharging.
2. Maintenance Free Batteries:
- These are sealed lead acid batteries that do not require electrolyte level check and top-up. They are safer compared to normal lead-acid batteries but, are costly. They also do not last as long as the latter.
3. Flat Plate Batteries:
- They have lower battery life but offer good battery backup. Their alloy plates are designed to work on low maintenance. Flat plate design makes the batteries compact, recyclable, and 100% sustainable.
4. Tubular Batteries:
- Tubular batteries are the most popular and efficient. They have a complex design yet last longer. These batteries need low maintenance and thus are expensive.
Each type of battery is best for a particular home setup. Here are a few hot-selling inverter batteries options that suit any environment-

Before buying any of these inverter batteries, certain points help you decide the best choice for your needs. Find a comprehensive buying guide for your reference below.
Inverter Batteries Buying Guide: How To Choose The Best Inverter Batteries?
1. Power Requirement:
Make a note of all the gadgets that need to run during a power cut. If you need 1 tube light, 1 fan, 1 TV and 1 CFL to be running on the inverter, calculate the total power requirement. In this case, it would be (1*50)+(1*90)+(1*120)+(1*50)=285 watts.
So, you will need an inverter battery that supports a minimum of 285 W. If the inverter battery cannot keep up with your requirements, it will breakdown due to an overload.
2. VA Rating:
Volt Ampere (VA) rating is the voltage and current supplied by the inverter to the appliances. Hypothetically, if an inverter operates with 100% efficiency, then the power requirement of the electrical items will be equal to the power supplied by the inverter. Thus, it is recommended to opt for inverters with an efficiency range from 60-80%.
It is obvious that the size of the battery should be identical to the size of the inverter. Mismatched sizing will render the inverter functionless/powerless.
4. Battery Type:
Between lead-acid, flare plate, tubular, and maintenance-free batteries, choose what suits your power requirement. Ideally, you should opt for quick charging, emission-free, and high-performance model.
However, not all battery types can support heavy home appliances like AC, fridge, and washing machines TOGETHER. Hence, discuss with the manufacturer/dealer/expert technician before making a decision.
Most vendors provide free replacement warranty for any inverter battery. In addition, a pro-rata warranty is offered where you pay a sum depending on the time when the battery stopped working.
If the battery that you bought has a warranty of 48 months (36 months FOC + 12 months pro-rata) and the battery fails to perform in the 39th or 40th month of purchase, then 75% will be deducted from the total price of the new replacement battery. This calculation is subject to change depending on the brand/seller.
With the help of these points, invest in robust and safe inverter batteries.
Say no to power cuts and work from home in peace!
Frequently Asked Questions (FAQs)
Ans: A 150Ah lead-acid battery provides 7.5 amps over a 20 hour time period. After 20 hours of continuous backup, you might want to recharge the battery for further use.
Ans: Unplug your battery from the inverter. Wait for 30-40 minutes. Measure the voltage across the 2 terminals of your battery. It should read 12.6-13 Volts which is the voltage of a fully charged battery.
Ans: On average, flat plate batteries work up to 3 years. The tubular ones can go up to 5 years. Within their lifespan, batteries can be easily damaged due to power outages, weather changes, and water loss.
Ans: Follow these steps to increase the life of your inverter battery-
Protect it from rust, dust, and water
Check the water level frequently
Replace the batteries when needed; do not delay
Install it in a well-ventilated area- away from fire and smoke
Disconnect extra load when not in use
Use energy-saving devices to reduce the load on the system
Allow reserve power to drain completely before recharging
Do not combine old and new batteries in a system.
